I have a beautiful boxer that is on her 42nd day of pregnancy and she had a little bit of clear discharge. She is acting normal as far as being pregnant increase of food, wanting to be loved on, slight weight territorial. Her nipples are now enlarged and she getting pretty heavy. Now, while she was in heat she had some discharge too. I took her to the vet to make sure she was ok to breed and he gave her some meds ran her blood and she was fine. He said that I should be ready to have some beautiful pups and this may happen with her while she is in heat but that isn't a problem. Should I be worried or am I overreacting?
